Pregnancy is the time before birth when kittens develop inside the mother’s uterus. Unlike canine fertility, feline fertility is influenced by the amount of time that the female is exposed to sunlight. As a result, pregnancy in cats tends to be seasonal, with most births occurring from spring through early fall.

Pregnancy is the time between conception and birth when puppies develop and grow inside the mother’s uterus. By day 40, the fetus has eyelids, claws, and hair, and the gender is apparent. While toy breeds tend to have smaller litters of one to four puppies, larger breeds may carry as many as eight to 12 puppies. After 56 and 70 days, or about 2 months, puppies are ready to be born.

Heartworm disease is serious and potentially fatal. It affects dogs, cats, and up to 30 other species of mammals. Heartworm disease has been reported in all 50 states. It is caused by parasitic worms (heartworms) living in the major vessels of the lungs and, occasionally, in the heart. Heartworms are transmitted (as microscopic larvae) through the bite of an infected mosquito. The scientific name for the heartworm parasite is Dirofilaria immitis.

During the birthing and nursing processes, puppies and kittens ingest bacteria that make themselves at home in the intestines. Some of these bacteria are beneficial to the pet, and some are potentially harmful. The beneficial bacteria help digest food, produce energy for the cells lining the digestive tract, and help with immune function. They also help keep the potentially harmful bacteria to a minimum.
